This overview combines information from different TechNet/Blog/Support pages to have the most interesting values in one table. I will maintain this page from time to time. However, it could happen that some values are outdated. If so, please leave a comment and I will update the table.
Note, that dates are specified in German notation (dd.mm.yyyy).

Most columns don't need to be explained. The Channel Switch column, which appears twice, specifies the version and the date of the CBB/SAC declaration for each release. Further information on servicing channels can be found here.
Always check the last modified date.
